HANDLE-BAR FOR CYCLES.

To all whom it may concern:

Be it known that I, NICOLAS GASTON BOUILLAT, a citizen of the FrenchRepublic, residing at Bron, Rhone, in France, have invented a certainnew and useful Improvement in Handle-Bars for Cycles, of which thefollowing is a specification.

The present invention relates to improvement in handle bars for cyclesand has for its object improved shock absorbing means applicable tocycle handle bars of the kind provided with a horizontal extension tothe vertical part of the handle bar or steering 30st. 9 i The improvedshock absorbing means suppress vibrations of the handle bar fatiguing tothe rider and absorbs shocks, which might be transmitted through saidhandle bar.

The annexed drawing illustrates the invention and shows a section of ahandle bar of the kind described, taken transversely through the centerof the handle bar proper and longitudinally through the extension. Thefront part of the horizontal extension 1 of the steering post 17 carriestwo lugs 2, one of which carries a hinge 3 on which is articulated acollar piece 4 which is fastened at 5 by a bolt 18 and nut 19 andincloses with a slight amount of play an elastic ring 6 forming a collarfixed to the handle bar proper 7. Between the two outwardly curved ends20 of the ring 6 is fixed, by means of a screw 8, the flattened end 21of a lever 9 articulated at 10 to a member 11 against the cup-shaped end22 of which the one end of a coil spring 12 bears. The other end of thisspring bears against a cupshaped abutment 13 which is normally fixed,but regulatable as regards its position to adjust the resistance of thespring. This regulation is obtained by means of a screw 14 screwedthrough a cap 15 and the said screw being fixed firmly in position by acounter nut 16 on the outside of cap 15.

The spring 12 normally maintains the handle bar in the positionillustrated.

It can be understood that during travel of the cycle, the shocks andvibrations borne by the extension 1 are greatly absorbed andSpecification of Letters Patent.

are only slightly transmitted to the handle bar as the latter isoscillatory and is provided with the cushioning means constituted by thespring 12 which is compressed when the handle bar drops.

A space 17 is provided between the lugs 2 to allow of the oscillatorymovement of the lever 9.

It is to be noted that the normal position of the handle bar can beadjusted to suit the riders requirements.

l/Vhat I claim as my invention and desire to secure by Letters Patent ofthe United States is 1. In a cycle steering bar, the combination of avertical member, a horizontal hollow extension thereto, a handle barcapable of oscillation about its axis, an elastic ring fixed upon saidhandle bar, lugs upon said extension and a collar piece secured to saidlugs and surrounding said ring, a lever con nected to said ring andextending into said extension, and spring cushioning means within saidextension and in connection with said lever for cushioning theoscillatory movement of the handle bar in one direction.

2. In a cycle steering bar, the combination of a vertical member, ahorizontal hollow extension thereto, a handle bar capable of oscillationabout its axis, an elastic ring fixed upon said handle bar, lugs uponsaid extension and a collar piece secured to said lugs and surroundingsaid ring, a lever connected to said ring and extending into saidextension, a member pivoted to said lever within said extension, a coilspring in said extension abutting with one of its ends against saidmember, an adjustable abutment for tensioning said spring, a screw capupon the free end of the horizontal extension and means carried by saidcap for adjusting the position of said abutment.

In witness whereof I have signed this specification in the presence oftwo witnesses.
